Yintoni iHEMC?

I-Hydroxyethyl Methylcellulose (HEMC) yi-derivative ye-cellulose ether esetyenziswa ngokuqhelekileyo njenge-agent agent, i-stabilizer, kunye ne-addition yokugcinwa kwamanzi kumashishini ahlukeneyo, ngakumbi kulwakhiwo, amayeza, kunye neemveliso zokhathalelo lomntu. Ngokufana ne-Hydroxypropyl Methylcellulose (HPMC), i-HEMC yenziwe ngokuphatha i-cellulose nge-ethylene oxide kunye ne-methyl chloride, okubangelwa i-compound kunye ne-hydroxyethyl kunye namaqela e-methyl afakwe kwi-backbone ye-cellulose.

I-HEMC yabelana ngeepropati ezininzi kunye ne-HPMC, kuquka:

1. Ukugcinwa kwamanzi: I-HEMC inamandla okufunxa nokugcina amanzi, okwenza kube luncedo kwizinto ze-cementous ezifana nodaka kunye ne-adhesives ye-tile ukukhusela ukomisa kwangaphambi kwexesha kunye nokuphucula ukusebenza.
2. Ukutyeba: Inokunyusa i-viscosity yokwenziwa kolwelo, okuluncedo kwizicelo ezinje ngeepeyinti, iingubo, kunye neemveliso zokhathalelo lomntu ukufezekisa ukuhambelana okufunwayo.
3. Ukuzinzisa: I-HEMC inceda ukuzinzisa i-emulsions kunye nokumiswa, ukuthintela ukuhlukana kwesigaba kunye nokugcina i-homogeneity yemveliso.
4. Ukuqulunqwa kwefilimu: Ngokufana ne-HPMC, i-HEMC inokwenza ifilimu encinci xa isetyenziswe kwiindawo eziphezulu, inika ukhuseleko kunye nokuphucula ukubambelela.
5. IiPropati eziPhuculweyo zokuHamba: Inokuphucula iimpawu zokuqukuqela kokwenziwa, ukuququzelela ukusetyenzwa kunye nokusetyenziswa.

I-HEMC isoloko ikhethwa ngaphezu kwe-HPMC kwizicelo ezithile ngenxa ye-viscosity ephantsi kunye nokunyibilika okungcono kumanzi abandayo. Nangona kunjalo, ukhetho phakathi kwe-HEMC kunye ne-HPMC luxhomekeke kwiimfuno ezithile zokuqulunqa kunye neendlela zokusebenza.

Isishwankathelo, i-HEMC i-derivative cellulose ether derivative kunye noluhlu olubanzi lwezicelo kumashishini ahlukeneyo, apho iipropati zayo njenge-thickener, i-stabilizer, kunye ne-agent yokugcinwa kwamanzi zixabiswa kakhulu.
